在固定模子中焊接鋼軌接头的工艺过程。是以焊縫控制成形的单程自动电渣焊和手工电渣焊两种方法为基础。在第一种場合下,焊縫的强制成形用水冷却銅板进行,第二种方法則利用耐火材料制造的固定模子。可拆开的固定模子(見图)由两半个耐火磚2和3組成。每一半的形状和尺寸与标准磚尺寸相同,耐火磚的內表面符合鋼軌的形状(軌頂、軌腰和軌底)。两半个 The process of welding rail joints in a fixed mold. Is based on the weld control forming one-way automatic electroslag welding and manual electroslag two methods based. In the first case, the forging of the weld is carried out with water cooled copper plates and the second method uses a fixed mold made of a refractory material. The detachable fixed mold (see photo) consists of two half-bricks 2 and 3. Each half has the same shape and dimensions as a standard brick, with the inner surface of the firebrick conforming to the shape of the rail (rail top, rail waist and rail bottom). Two and a half
